Yes, you are absolutely correct... its because there WAS no cpu hierarchy
a few weeks ago... it was a machine-only hiearchy. I created the cpu
hiearchy and I've been slowly moving the cpu-specific code from pc32
into it on an as-needed basis (i.e. code that both VKERNEL and PC32 need).
I'm going to hold off on any commits for a day or two so we can discuss
the system-call vs userland issues a bit more. I am not leaning to either
side, really. In my view it is ok to have a few system calls that
later become obsolete... that's what the COMPAT options in the kernel
build are for.
